반응 단계
To a solution of indole-2-carboxylic acid (1e: 1 mmol) in DMF (4 mL) was added DIPEA (2 eq.) followed by HATU (1.2 eq.). The mixture was stirred for 15 minutes before the desired amine (R6—NH2) was added. The mixture was left to stir at room temperature for 5-16 hrs before saturated NH4Cl solution was added. The mixture was extracted with ethyl acetate and the combined organic extracts were washed with water and brine, dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The crude material was purified on CombiFlash® purification system (Teledyne Isco) using appropriate mixtures of ethyl acetate and cyclohexanes to obtain the desired product indole-2-carboxamide (I).
